Hinge



Feb. 20, 1951 Y L. MAURATON HINGE Filed Sept. 8, 1948 IN VE N TOR MA URA TON ORNEYS Patented Feb. 20, 1951 UNITED STATES FATENT OFFICE Application September 8, 1948, Serial No. 48,171 In France September 11, 1947 1 Claim.

Loose butt hinges are normally constructed in such a manner that those intended for application, for instance, to the left-hand side of a door jamb to carry a door opening to the left cannot be used at the right-hand side of the door jamb to carry a door opening to the right. Each such hinge is therefore restricted to use for the particular direction of opening for which it was designed.

The object of the present invention consists in the construction of loose butts which by their particular method of construction can be used optionally in both directions either left or right. It is essentially characterised by the use of a removable pintle which permits the changing of direction and a closing tip which is likewise interchangeable.

The pintle and tip have the same screw-thread as that which is provided at the upper and lower extremities of the knuckles of the butt leaves, whereby the pintle and tip can each be engaged in either leaf knuckle. It is thus possible to change the direction of the butt by placing the pintle at the portion of the butt which receives the tip or inversely. This construction furthermore permits the manufacture of merely a single type of butt member which results in a considerable economy. The assembly of this loose butt has an absolute homogeneity in all its portions and a robustness resulting from its arrangements and from the displacement of its fixing screws. The fixing is likewise very rapid.

On the annexed drawings is given by way of non-limiting example one of the forms of construction of the object of the invention;

In this drawing:

Figs. 1 and 2 show an elevation of the threaded pintle and tip.

Fig. 3 shows an elevation of the loose butt with the members sectioned along the line 3, 3 of Fig. 4 indicating the positioning of the pintle and tip when the loose butt is to be placed at the lefthand side of a lift-off type door.

Fig. 4 is a plan view of the loose butt as applied to a door Jamie and a door which is arranged to open to the left.

Fig. 5 shows an elevation with the members sectioned along the line 55 of Fig. 6, indicating the positioning of the pintle and tip when the loose butt is to be placed at the right-hand side of a lift-off type door.

Fig. 6 is a plan view of the loose butt when suitably re-arranged and applied to a door jamb and a door adapted to open to the right.

The tip I, Fig. l, is placed at the upper part of i the butt and comprises a screwing head 2 and a screw thread 3.

The pintle i, Fig. 2, likewise comprises a screwing head 5 and a screw-thread 6 at its lower part; the smooth upper part 1 forms the fixed spindle on which takes place a movement of rotation of the upper leaf.

The butt of Fig. 3 comprises two leaves 48 and 9 provided with perforations ID and II to be placed either on the jamb or on the door. In this example, the leaf placed on the jamb l2 Fig. 4 receives, screwthreaded on its knuckle I3, the pintle I which receives and guides the leaf 9 to be fixed on the door l5 Fig. 4. The pintle 1 is maintained in its definite position by its screw threading 0n the lower portion of the lug 8.

The leaf 9 has at its upper part the tip I which screws thereto and assures the watertightness of the whole.

This same loose butt could be used in the inverted direction, for which the leaf 9 would be placed in place of the leaf 8, and the tip I would be unscrewed and put in place of the pintle 4. Inversely one could screw onto the upper part of the leaf 8 the closing tip I.

Thus, one would have inverted, by a simple changing of the keying, the direction of development of opening, and the same members, see Fig. 6, according to the direction of the keying, can be used to construct a loose butt opening or closing in either a rightor 1eft-handed direction, as required. There is thus realised a possibility of manufacture of a single kind of member, but the forms, dimensions and dispositions could be varied without thereby changing the general conception of the invention which has just been described.

I claim:

In a butt hinge, a leaf to be attached to a door jarnb, another leaf to be attached to a door, a knuckle for each of said leaves, a bore partially screw-threaded in each of said knuckles, a screwthreaded pintle to engage with the screw-threading of one of said partially screw-threaded bores and extending therefrom to form a pivot for the other leaf, and a screw-threaded tip to engage with the screw-threading of the other of said bores, the pintle being engaged in the screwthreading of the lowermost leaf and the tip engaging with the sorew-threading of the uppermost leaf, whereby the butt hinge may be arranged with either leaf uppermost to permit its use at either side of the door.
